Isogeometric analysis (IGA) developed by Hughes et al. [1]} can be used
to implement multiple boundary conditions[2]}, [3]}, [4]}, [5]}, [6]} as opposed to other
approximate energy method formulations. Hence, beam problems with
multiple support can be tackled using this approach. Moreover, the
numerical solution obtained by IGA is expected to give
a better convergence due to its k refinement capability as shown by Nguyen [7]}.
The solution does not oscillate with an increase in the polynomial order as
opposed to the polynomials used in the conventional finite element polynomial shape
functions.
